Resource Abstract:
- description: This part of DS 781 presents data for the habitat map of the seafloor of the Offshore of San Francisco map area,
California. The vector data file is included in "Habitat_SanFrancisco.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreSanFrancisco/data_catalog_OffshoreSanFrancisco.html.
Using multibeam echosounder (MBES) bathymetry and backscatter data, potential marine benthic habitat maps were constructed.
The habitats were based on substrate types and documented or "ground truthed" using underwater video images and
seafloor samples obtained by the USGS. These maps display various habitat types that range from flat, soft, unconsolidated
sediment-covered seafloor to hard, deformed (folded), or highly rugose and differentially eroded bedrock exposures. Rugged,
high-relief, rocky outcrops that have been eroded to form ledges and small caves are ideal habitat for rockfish (Sebastes
spp.) and other bottom fish such as lingcod (Ophiodon elongatus). Habitat map is presented in a map format generated in a
GIS (ArcMap), and both digital and hard-copy versions will be produced.; abstract: This part of DS 781 presents data for the
